Set a guard, O LORD, over my mouth; keep watch over the door of my lips!
English Standard Version (ESV)
David recognizes that his own strength isn't enough to control his tongue, especially when facing intense pressure and provocation. He's not just asking for help avoiding any bad words, but specifically praying for protection against the kind of unadvised, impatient, or compromising speech that enemies could exploit or that would dishonor God in a foreign, hostile land.

This passage echoes the same sentiment, highlighting that guarding one's speech is a sign of wisdom and self-control, directly relating to the Psalmist's plea for a 'guard' over his mouth.

He strove to "keep his own mouth with a bridle" - to " be dumb with silence, and hold his peace" - but this was not always possible for him of his own unassisted strength. He therefore makes his prayer to God for the Divine help.
